LOCKER.

Specification of Letters Patent.

1 atented Apr. 6, 1915.

Application filed. August 10, 1914:. Serial No. 856,063.

T0 all whom 'it may concern Be it known that I JOHN GRIESMAIER, acitizen of the United States, residing at Ghicago, inthe county of Cookand State of Illinois, haveinvented certain new and useful Improvementsin Lockers, of which the following is a specification.

The locker which is the subject matter of the present application forpatent is designed more particularly for use in hotels, restaurants,barber shops and similar places, its object being to provide a safeplace for the customers wraps, hat, umbrella., etc.

The invention also has for its object to provide a novel and improvedcoin or checkcontrolled lock for the locker.

In order that the invention may be better understood, reference is hadto the accompanying drawings, in which- Figure 1 is a perspective viewof the locker; Fig. 2 is an enlarged vertical section thereof; Figs. 3and L are elevations of the doors forming the closure of the locker;Fig. 5 is an elevation, partly in section, showing the lock; Fig. 6 is aview similar to the preceding, showing the parts in another position;Fig. 7 is a horizontal section on the line 7-7 of Fig. 5; Fig. 8 is ahorizontal section on the line 8-8 of Fig. G; Fig. 9 is a face view ofthe coin or checkcontrolling means of the lock, and Fig. 10 is aperspective view of a portion of the lock housing.

Referring specifically to the drawings, the locker is a tall boX-likestructure having sides 12, a back 13, a top 14 and a bottom 15. Thefront wall of the locker comprises top and bottom sections 16 and 17,respectively, which are spaced to provide an opening through whichaccess is had to the interior of the locker. This opening is providedwith a closure comprising two sliding doors 18 and 19, respectively. Inthe locker, a short distance above the bottom 15, is a false bottom 20,beneath which is located a shallow pan or dra-wer 21, slidable into orout of the locker through an opening in the bottom front wall section17. The false bottom has perforations 2Q, and its purpose is to supportan umbrella, the latter being stuck into one of the perforations 22. Ifthe umbrella is wet, the drippings will be caught in the pan 21.

The doors 18 and 19 are screened as shown in Figs. l to 4, and theyslide, one in front of the other, in grooves 28 formed by strips on theside walls 12, said grooves being separa-ted by a parting strip 21. Onthe inner face of the top and bottom rails of the lower door 19 arelongitudinal ribs 25, and on the outer face of the top and bottom railsof the top door are longitudinal ribs 26. l/Vhen the two doors are slidupward to closing position, the top rib 25 and the bottom rib 26 meet,and if the upper door 18 is locked, the lower door is held by the ribsfrom being slid downward to open position. All the ribs, except thebottom rib of the lower door stop short of the side edges of the doorsso that they may clear the parting strips 21, and said bottom rib servesto prevent the lower door from being slid upward after it reaches itsclosing position, said rib being then in contact with the bottom of theparting strips, the latter therefore serving as stops to limit theupward travel of the lower door. The parting strips do not extend downto the bottom of the door way but stop a suilicient distance thereabove,so that when the doors are slid downward to open position, they seatbelow the parting strips as shown in Fig. 2. In order to cushion thedoors when they are slid down to open position, a rubber or othercushion 27 is mounted at the bottom of the door way.

The locker will be provided with suitable garment hangers, as shown inFig. 2.

rlhe following check or coin-controlled locking mechanism is provided:On the outer face of the top section 16 of the front wall of the locker,over an opening in said section, is mounted a plate 2S, on the back ofwhich, and consequently on the inside of the locker, is a coin chuteformed by laterally spaced, parallel vertical ribs 29 and a cover plate30 extending across the latter. The ribs form the side walls of the coinchute and their upper ends, where the coin or check is inserted, areflared as shown at 31 and project from the top 14 of the locker. In theentrance end of the coin chute are mounted two opposed bowed springs 32which accelerate the drop of the coin or check. rIhe springs spread asthe coin or check is inserted, and when the latter is forced past thesprings, they draw together and snap the coin or check down the chute.At the bottom of the coin chute is an inclined shelf 38 which deiectsthe coin or check into a receptacle 34 hinged at its rear end, at 35, inan opening in a horizontal partition 36 mounted in the upper portion ofthe locker, and cutting off this p'artof the locker from the other partin which the garments, etc., are placed. A suitable lock 37 is providedfor holding the receptacle up. Upon unlocking the receptacle and tiltingit down, as shown dotted in Fig.V 2, and opening the doors 18 and 19,access may be had to the coins or checks in the receptacle.

1n the plate 28 is a key hole or slot 38, and below the latter the platehas an aperture 39 for a bolt 40 carrying a chain 41 which is connectedto the upper door 18 and is of such length that when said door is closedand the bolt is in place and locked, said doorcannot be slid down toopen position. The opening of the lo-wer door 19 is prevented by themeans hereinbefore described. Y

On the back of the plate 28, to one side of the coi-n chu-te, is mounteda vertical slide 42 comprising` a flat plate held in place betweenundercut guide ribs 43 on the plate 28. The slide has a vertical slot 44divided by a cross bar 45 into upper and lower sections, the top of theformer being reduced in width, as indicated at 46. The upper slotsection registers with the key hole 38, and the lower slot sectionregisters with the aperture 39. The lower end of the slide reduces to anarrow strip 47 having an outstanding flange 48.l Y

To the back of the plate 28 is pivoted a lever, one end 50 of which isbelow and in line with the coin chute so as to intercept the check orcoin falling down the chute. This end of the lever is widened so thatthe check or coin may not miss the same. The other end 51 of the leveris positioned so that it is in contact with the flange 48. The end 50 isnormally positioned across the lower end of the coin chute. A check orcoin dropping down the chute, upon striking the end 50, tilts the lever,so that the end 51 swings upward, andas said end engages the flange 48,the slide 42 is carried upward. As the coin clears the lever, it dropson the shelf 33 and is deflected intoy the receptacle 34.

Against the back of the plate 28 is mounted a housing which incloses andsupports the remaining parts of the lock which will now be described.This housing comprises two laterally spaced vertical plates 52 and 53,respectively, having at their rear vertical edges outstandingy flanges54 which are bolted or otherwise secured to a supporting arm 55 carriedby the back 13 of the locker. The forward vertical edge of the plate 52abuts against the back of the plate 28 over the slide 42, said edgehaving a recess 56 to accommodate the Slide.

On the plate 52 are mounted' two vertically spaced, horizontal guidestrips 57, the

plate 52.

spacebetween the same being in alinement with themkey hole 38. To therear of these guide strips' isy mounted a series of main tumblers, whichare angular, each tumbler comprising two arms 58 and 59, respectively.The tumblers are pivotally mounted, side by side, on'a pin or stud 60carried by the The arms 58 of the tumblers point upward, and the arms 59are horizontal and point toward the slide 42. The upper end of the arms58 are in line ,with the ace between the may be engaged by the key 61,said ends being reduced. to different widths and the inner end of thekey being correspondingly shaped as shown at162, in Fig. 8. Thus aspecial key, corresponding to the arrangement of tumblers, or thecombination, is necessary. The proper key, when inserted through the keyhole 38 and pushed against the upper ends ofthe tumbler' arms 58, willswing the latter as one on the pivot 60. The strips 57 guide the key tothe tumblers.

The tumbler arms 59 have bottom hooks 63 at their forward ends to engagean abutment 64 on the inner end of the bolt 40 and thus preventwithdrawal of the latter. However, when the tumblersare operated todisengage the hooks from the abutment, the bolt may be withdrawn and thedoor 18 is then free to be slid down to open position. The plate 53carries a guide 65 for the bolt.

Above the arms 59 of the main tumblers is mounted a series of auxiliarytumblers 66, which are substantially U-shaped, the two branchespointingl downward. These auxiliary tumblers are pivotally mounted atthe connecting portion of their branches on a pin or stud 67 carried bythe plate 52. The rear branches seat on the top edges of the branches 59of the main tumblers, said edges being slightly recessed to form a seat,as shown at 68. The forward branches of the auxiliary tumblers terminatein a forwardly extending finger 69 designed to enter thel slot 44 toengage the bottom of the cross bar 45 and hold the slide 42 elevated.When the fingers 69 are withdrawn from the cross bar, the slide isreleased so that it may drop by gravity.

The function of the slide 42 is to prevent withdrawal of the key 61after it is inserted in the lock; The shank of the key, adjacent toitsbow or handle has a reduced neck portion 70 forming transverse notchesin opposite edges of the shank. The opposite side walls of the reducedupper end 46 of the slot 44 are designed to seat in these notches,

key cannot be and when thus seated the withdrawn. v

Proper return springs 71 for the main and auxiliary tumblers areprovided. The main tumblers swing between stop lugs 72 on the .Y

plate 52. y Y Y.

O'n the plate 53' is an outstanding horizontal rib 73 positioned to seatin a longitudinal side slot 74 in the bolt 40 when the latter isinserted into the lock. r1`hus, the bolt can only be inserted one way,which is sure to be the proper way. The bolt also has a bottom rib 75 totake a reduced bottom portion 7 6 of the aperture 39, which preventslateral motion of the bolt which might injure the main tumblers.

A pin 77 carried by the plate 28 and extending into the slot 44 servesas a stop to prevent the slide from dropping down too far.

lThe key hole 38 has a reduced bottom portion 7 8 which acts inconjunction with a lug 79 on the under side of the key 61 to insure theproper insertion of the key.

The operation of the lock may be summariZed as follows: When the bolt 40is out of the lock, the door 18 is free to be slid down to gain accessto the locker. The coin actu ated lever 50, 51 is normally in the dottedline position shown in Fig. 9, the slide 42 being down and the part 46of the slot 44 locking the key 61 in the key hole 38. The last previousinsertion of the key operated the main and auxiliary tumblers and placedthe same in the position shown in Fig. 6, the main tumblers having beenswung to release the bolt, and the auxiliary tumblers having been swungto release the slide so that it was free to drop down to lock the key.The lock is now inoperative as the key cannot be removed. lt a personnow wishes to use the locker, and after placing the garment, hat, etc.,therein, he drops a coin or check of the required denomination into thecoin chute, and after raising the doors 18 and 19, the bolt is inserted.As the coin or check drops down the chute and strikes the part 5() ofthe lever, the slide 42 is pushed upward to release the key, and thebolt is locked by the hooks 63 of the main tumblers. The lingers 69 ofthe auxiliary tumblers also come under he cross bar to lock the slideagainst downward movement. rIhe bolt is now locked, and the key may beremoved and kept by the person using the locker until said person wantsto remove the garment, hat, etc., the parts being in the position shownin Fig. 5. To unlock the bolt, the key is inserted to operate the maintumblers, whereupon the parts again assume the position shown in Fig. 6,and the bolt is unlocked, the key being again locked as hereinbeoredescribed. The bolt being unlocked, it may be withdrawn to open thelocker doors, and the parts are now ready for the next Person desiringto use the locker.

It will be seen from the foregoing that G'opes of this patent may beobtained for the locker doors cannot be locked without inserting a coinor check. 1f a key is lost or stolen, the lock can be opened to changethe combination and a new key supplied, thus rendering the original keyuseless.
